Animation is a bit odd and random. :) Its cool though keep it that way, I just really dislike that model but I assume there are no proper alternative harvester models out there. Loved the arabic music by the way. ;)

Btw, are you planning on using features from tiberian sun regarding tiberium spread? "a tiberium "pod" will send out "roots", which create more pods. Tiberium also spreads by infecting trees and mutating them into so-called "Blossom Trees", which seed the substance across large areas of land. Destroying a Harvester, Refinery, Cyborg, Tiberium Spike, or other Tiberium-containing unit or building can cause a small amount of tiberium to be released."

There's also tiberium wildlife, as specified in this wiki.Cnc.wikia.com

Please note that the CC4 Visceroids sucked. ;P
There's also multiple forgotten units that could be added.

Not trying to push extra work on you though, just pointing out things that would be cool.

Sorry, for posting multiple posts like this, but one final thing. If you ever need or want help, send me a message. While I've generally only modded warcraft 3 by creating models and whatnot. It would be interesting to join the modding of Red Alert 3 as well.

Here's an example of what I've done for that in case if you're interested in getting help. My alias on that site is MiniMage.
